GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 176) = 69168
GCD(393, 176) = ( 393 x 176 ) / 69168
= 393 / 176
= 393
Step2:
LCM(1, 817) = 817
GCD(1, 817) = ( 1 x 817 ) / 817
= 1 / 817
= 1
Step3:
LCM(1, 171) = 171
GCD(1, 171) = ( 1 x 171 ) / 171
= 1 / 171
= 1
So, Greatest Common Divisor of 393, 176, 817, 171 is 1
